LEG-WARMING BOOT.

To all whom t may concern:

Be it known that I, WILLIAM O. Mosson, a citizen of the United States, residing at Looneyville, in the county of Roane and State of West Virginia, have invented certain new and useful Improvements in Leg- Warming Boots, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to warming appliances, and particularly to a leg and foot covering of such a construction as to constitute a boot which may extend either above the ankle, extend to the knee or above the knee, as may be desired.

The general object of my invention is the provision of a device of this kind having a double wall, the space between said walls being adapted to be filled with hot water, steam or other heated fluids.

A further object of my invention is the provision of a leg warming boot having an inside stocking, as it may be termed, of water-proof material, and the boot being adapted to receive fluid in a heated condition, and in this connection to provide means whereby the leg of the boot may be held to the leg of the wearer.

Still another object of my invention is to construct this boot so that while hot water may circulate beneath the sole of the foot yet there shall be rm support for the sole.

Still another object is to so construct the boot that it may be lled with hot water or either attached to the exhaust of an automobile engine or to a source of steam or other heated fluid.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of the warming appliance in actual use; Fig. 2 1s a vertical sectional view of the warming boot; Fig. 3 is a section through the sole portion thereof.

Referring to these figures, 10 designates what I will term the inner stocking. This is to be made to conform to the leg and foot of the wearer and of course may be of such size as to extend either just above the ankle, to a point below the knee or above the knee, as desired. This inner stocking is preferably made of linen, canvas or other suitable material rendered water-proof by being coated or impregnated with rubber, the rubber being vulcanized. The inner stocklng should be soft and iexible, and is preferably lined with flannel which is designated l1. A

Disposed exteriorly of the stocking 10 is the boot or outer casing, designated 12. This is also made of any suitable fabric coated or impregnated with rubber so as to be entirely water-proof. The upper end of this outer wall or boot is connected. to the stocking 10 at a point below the upper end of the stocking. The boot entirely surrounds the stocking and is spaced therefrom at all points, but the sole 13 of the boot supports and is connected to the stocking by a plurality of connecting members, which, while affording firm support for the foot of the wearer will permit circulation of water or other iuids between the sole of the shoe and the sole of the stocking. To this end I have shown the sole 13 of the shoe as formed with transversely and longitudinally extending ribs 14 which may be made of rubber or other suitable material and which are preferably integral with the rubber of the sole of the boot and the rubber of the stocking. These ribs are formed with perforations, and preferably in these perforations are inserted the thimbles 15 or small tubes permitting the circulation of water beneath the foot of the wearer. Preferably the sole 13, which is made of relatively heavy rubber or which may be made of leather, has an upwardly extending flange 16 at its edge conforming to the outline of the foot, the ribs 14 extending across and merging into said lia-nge.

The upper end of the boot is formed with a filling opening 17 closed by a screw threaded stopper 18.. The stocking 10 extends above the upper end of the boot and is provided with any suitable means whereby it may be engaged with the leg of the wearer. To this end I have shown a strap 19 which extends around the stocking, this strap preferably passing through loops 20 formed upon the stocking. It will be obvious that the tightening up of this strap at the leg portion of the device may be held raised so that there will be no downward pull upon the leg of the boot or stocking. Preferably there will be a space of about one inch between the outer boot and the inner i the lower end of the boot at the heel thereof is formed with a thimble 21, interiorly screw threaded and normally closed by a plug 22 but adapted to be connected to a nipple 23 formed upon the extremity of the pipe 24 which may extend to any suitable source of heated fluid, such for instance as the eX- haust pipe of aninternal combustion engine or to a source of steam or hot air. This thimble 21 also forms a drain pipe whereby the water contained within the boot may be readily drained ofl. It will of course be understood that the pipes 24 may be sufficiently flexible to allow a certain amount of movement to the feet of the wearer.

My improved leg and foot Warmer is to be made of light weight material when wanted for use on a pat1ent'lying in bed, but is of course to be made of heavier and more serviceable material for out of door use. It is particularly adapted to be worn when riding-in cold wather, but may also be used to .apply heat to the leg of a patient who has the grippe, gout, rheumatism, or cold feet.

While I have illustrated this device as being particularly designed to be placed upon the foot and leg, it is of course obvious that it may be modified so that it may be placed around the hands and arms. While the foot and leg warmer may be designed to fit the leg snugly, it is obvious also that it may be large enough so that the user may slip his booted feet into the warmer without trouble. It is particularly true where the warmer nly extends upward a relatively short height tums 14 in the sole, the foot will be firmly supported and the` boot can be used for walking shorty distances, while at the same time means is provided for circulating the heated fllpid between the foot and vthesole of the s oe.

While I have illustrated a boot having a leg portion designed to extend to the knee of the wearer, it is obvious that the proportions of this boot and the details of construction may be variedlin many4v ways without de arting from the spirit of my invention. aving described thev invention, what I claim is:

1. As an article of the 'character described, a double-walled boot, each wall comprising a leg portion and a sole portion, the walls being spaced from each other, the inner sole being spaced from the outer sole by solid members permitting a circulation of the fluid between the inner and outer soles, and means wherebyheating fluid may be filled into the space between the outer and innerv Walls. y

2. A heating article of the character described comprising an inner Wall of flexible water-proof material, an outer wall spaced therefrom and also of flexible water-proof material, the outer wall being less in height than the inner wall and attached thereto at its upper margin, the space between the outer and inner walls being adapted to be filled with heating fluid, a leg embracing strap mounted upon the inner wall above the outer wall and extending around the inner wall and adapted to hold the device in position upon a member, the outer wall being formed with a filling opening having a closure. Y

3. A heating boot of thel character described comprlsing an inner water-proof `stocking of flexible material, an outer wall spaced from the'stocking and also formed of relatively flexible water-proof material, the stocking and the outer wall being both formed with soles held in spaced relation by relatively solid elements formed to permit circulation of fluid between the inner 'and outer soles, the outer wall being connected to the stocking below the upper edge thereof, 'and' a band surrounding the upper edge of the stocking and adapted to be engaged with the leg, the outer wall being formed at its upper end with a filling opening having a closure and .at its lower end adjacent the heel with an opening having a closure.

4. A heating boot of. the character described comprising an inner water-proof stocking of flexible material, an outer wall spaced from the stocln'ng and also formed ofrelatively flexible water-proof material, the stocking and the outer wall being both formed with soles held in spaced relation by relatively solid elements formed to permit circulation of fluid between the inner and outer soles, Vthe outer wall being connected to the stocking below the upper edge thereof, and a band surrounding the upper edge of the stocking and adapted to be engaged with the leg, the outer wall being formed at its upper end with a filling opening having a closure' andv at its lower end adjacent the heel with an opening having a verse and longitudinal perforated members, opening having a screw threaded thimble, l@ the outer wall being less in height than the and a plug normally closing this thimble. l inner wall and attached thereto at its upper In testimony whereof I hereunto aflix my edge, mezisfadjacent the uppgr edge of tile signature in the presence of two witnesses. inner wa or supporting a oot upon t e le of a wearer, the outer wall being formed WILLIAM O MOSSOR with a filling opening normally closed by a Witnesses:
